The best productivity extension for people who open too many tabs

"Just close your tabs" isn't advice, it's a diagnosis you already knew. The actual reason a browser window ends up with forty tabs open isn't a lack of discipline, it's that every one of them got opened to answer a question ("is this the doc I need," "is this the right thread," "is this video worth watching") that couldn't be answered without opening it first. Fix the "have to open it to know" part, and the tab count takes care of itself.

Tab managers vs. tab prevention

Most productivity extensions in this space manage tabs after the fact: grouping them, suspending inactive ones to save memory, or giving you a searchable list of what's open. Those are real features, but they're cleanup, not prevention. The tabs still got opened. Peekly is aimed earlier in the process: if you can tell what a link is before you click it, a huge fraction of those tabs never need to open at all.

Where this actually saves time

• Comparing five product pages or five recipes without keeping five tabs alive to compare them
• Skimming a page of search results in Feed view instead of middle-clicking every promising one
• Watching a YouTube video from a linked-to timestamp while you keep working, floating above every other app instead of pinned to one browser tab
• Stepping through a list of results with arrow keys instead of opening, reading, closing, and re-finding your place in the list each time

What it doesn't try to fix

If your habit is genuinely archival — forty reference tabs you intend to read "eventually" — no preview tool fixes that, because those aren't unknowns you need answered, they're a backlog. Peekly is built for the other kind: the tabs opened purely to find out what's in them. If that's most of what's piling up in your window, that's the part this actually addresses.
